RESUMO

Pakistan's power sector has undergone extensive reforms to improve its technical and monetary performance over the last two decades. However, despite its fast-growing and hazardous nature, safety research remains limited in this context. This study aims to address this gap by assessing the level of safety climate in the power sector and comparing the safety climate in plants operated by multinational companies (MNCs) and local companies (LCs).To this end, five power plants operating in the southern part of the Punjab region (in Pakistan) were included in this study. The Nordic Occupational Safety Climate Questionnaire (NOSACQ-50), an analytical tool comprising of 50 items across seven dimensions, was used to determine the level of safety climate. An independent T-Test was then applied to compare the means in two different setups to draw a conclusion about overall safety climate differences. In MNCs, overall management/leadership perception improved; however, workers in both setups responded similarly in many cases. The lowest observed score in both setups was related to worker's prioritization of safety and risk non-acceptance. The study highlights the importance of a company's policies, procedures, and leadership commitments in creating a stronger safety climate by instilling trust in workers. The study further demonstrates that cross-cultural and strong policies devised by multinational companies help to improve the overall safety climate andconcludes that promoting an efficient and positive safety climate in the power sector is a long journey and that can only be achieved if all workers and leaders take on an active role.

RESUMO

Diffuse pesticide pollution through tobacco fields is a serious threat to both natural integrities and living beings because tobacco is known as a pesticide-intensive crop. Upsurge in the knowledge of detrimental impacts caused by organochlorine pesticides (OCPs) has made them a burning issue particularly in developing countries. Pakistan is a country famous for its agro-based economy and simultaneously is the second most significant pesticide consumer in South Asian countries. The studied area is tobacco hub of the country. Thus, the present work is aimed to investigate the contamination profile that highlights the ecological and health risk posed by OCPs in River Barandu, located in the proximity of tobacco farming region. ΣOCP levels in sediments ranged between 32.918 and 98.810 ng/g and in water between 0.340 and 0.935 µg/L. Hexachlorocyclohexanes (HCHs) and heptachlor were the most prevailing pesticides in both matrices of the river. Isomeric composition of DDTs and HCHs highlighted that the ß-HCH and p,p'-DDT were dominant isomers in water, while α-HCH and p,p'-DDT in sediment compartment. Enantiomeric compositions of HCH and DDT indicate both recent and historic uses of these compounds in the area. Indirect contamination through nearby tobacco clusters has been depicted through spatial analysis. Ecological risk assessment based upon the risk quotient (RQ) method revealed that α-endosulfan, dieldrin, heptachlor, and ∑HCHs represent a very high level of ecological risks. The OCPs' lifetime carcinogenic and non-carcinogenic health risks associated with dermal exposure to river's water were considered nominal for surrounding populations. However, detailed ecological and health risk studies are recommended considering the bio-accumulating nature of these contaminants in the food chain.
